From 84176663e70d93836d30d2a480a4201c7f790b42 Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Thu, 11 Nov 2021 14:19:33 +0800 Subject: [PATCH] drm/amd/pm: create a new holder for those APIs used only by legacy ASICs(si/kv) Those APIs are used only by legacy ASICs(si/kv). They cannot be shared by other ASICs. So, we create a new holder for them.
